    Re: Sharp AR-507 blank prints

    Most likely cause is a gear in the main drive is broken the part number is ngerh1284fczz. if you take cover off from right side you can see the coupler that drives the dv unit. run a copy and see if it turns

        I opened right side cover, and found the connection that drives the developer unit is actually rotating, but the motor on toner hopper unit is slipping against and wheels beside it. I thought there were too much toner, so I pull out half, and took off the motor and put it back on. all look ok but the motor still unable to drive the little wheels beside it. wondering what's the problem

            I'm reading back through the thread, and I don't remember if you've got a good latent image or not.
            Here are a few database entries that might be appropriate:

            Blank copies. No paper jams on AR-285, AR-505. The customer turned the bed handle ~90 degrees past the end of the travel. The bed does not stay up. The wiring to the pre-transfer lamp is damaged. Replace the bent roll pin for the rear lift arm. Install 1.5mm shim between the front bed frame and the E-clip to prevent future damage. Repair any damaged wiring to the pre-transfer lamp. Advise the customer that the handle only turns from 6:00 to 9:00.

            Very light gritty copies. "Add Toner". "Replenishing Toner" indication. Adding toner does not help. Gear noise, on AR-335. Bearings inside mag roller sieze, spinning the magnets & dumping developer. Broken gear 28T in main drive assy. The developer is extremely overtoned, just not stirred. Clean up the toner/developer spill. Replace the main drive assembly (CFRM-0939FC53), developing unit (CBOX-0116FCE1), and developer (AR-336ND).

            =^..^=
            If you'd like a serious answer to your request:
            1) demonstrate that you've read the manual
            2) demonstrate that you made some attempt to fix it.
            3) if you're going to ask about jams include the jam code.
            4) if you're going to ask about an error code include the error code.
            5) You are the person onsite. Only you can make observations.

                DV unit tends to go bad on this model, you may find that you need to replace DV unit or rebuild it.

                    Thank you guys so much!!!!!

                    finally fixed it.

                    Magnetic roller was stuck, and had to clean the crap out.

                    thanks again!!!

                        Another question,

                        this machine gets paper jam really often, so i'm setting SIM 50 -2 to lower down the contact pressure resistance, am I on the right track? anyone has any suggestion?

                            I'd start with pickup/feed/separation rollers first. I have not ever had to adjust buckle on the Cougar series. If it helps at all it will just temporarily disguise some other jamming problem. What codes? =^..^=

                                            This would be a great time for you to buy a manual.

                                            Misfeeds (jam code TRAY1, PPD1_ST1, PPD2_NT1) from tray #1, no paper is found. Recent toner spill on AR-250, 335. (Tray #1 jam, upper vertical path jam, pre-registration jam). Toner is spilled on the tray #1 feed tires. Clean up the toner spill. Clean or replace the tray #1 PF tires (NROLR1219FCZZ, NROLR1218FCZZ, NROLR1229FCZZ).
